Also known as a gnu, the blue wildebeest is potentially the ugliest of the antelope species.  It has a black face, and a slate grey-coloured coat, with a dark mane on its neck and under its chin and throat. Both males and females have wide, flattened horns. 

Wildebeest are grazers, and their wide muzzle is perfect for close, rapid feeding on short grass. 

They favour the open plains, but as they need to drink daily, they are limited to grazing land within a short distance from available water.

Distant thunderstorms can stimulate a migration of over 50km to find the resulting new, lush grassland.  

Herd Behaviour

Wildebeest form herds, which are normally dominated by one territorial bull.  A single male can command a harem herd of up to 40 females. 

Herds are active in the cool early mornings and late afternoons only, and during the heat of the day will rest.

Calves are born during a 3 week period only every season, just before or at the start of the most reliable rainfall.   A single calf is born, and can stand within 15 minutes. 

Young male calves leave the herd at about 2 years old, and form bachelor herds until they themselves become territorial, at around 4 - 5 years old.
